UV/TiO2 photocatalysis has been employed effectively for these organic dyes removal from dye-house effluent. This process produces less amount of ...
Our goal is to use our experience in combination with renewable energies and new technologies to stand up for a “green and sustainable future”. We want to inspire the social change in a resource-saving, intelligent and goal-oriented action. To be powered by nature!
When natural gas is burnt, it provides heat energy. But a waste product alongside water is carbon dioxide, which when released into the atmosphere contributes toclimate change. Burning hydrogen does not release carbon dioxide. What's the difference between blue hydrogen and green hydrogen?
4.1.2.1Hydrogen Energy Storage (HES) Hydrogen energy storageis one of the most popularchemical energystorage[5]. Hydrogen is storable, transportable, highly versatile, efficient, and clean energy carrier[42]. It also has a highenergy density. As shown inFig. 15, forenergy storage application,of...
Hydrogen is recognised as an important future energy vector for applications in many sectors. Hydrogen is an indirect climate gas which induces perturbations of methane, ozone, and stratospheric water vapour, three potent greenhouse gases. Using data from a state-of-the-art global numerical model, ...
Connecting Hydrogen Europe 2025 (CHE2025) is Europe's largest green hydrogen event. Join 6,000+ attendees and 100+ exhibitors at IFEMA Madrid, June 18-19, 2025, to drive the hydrogen economy forward. Discover groundbreaking solutions, network with indust

Due to their use of water, a readily available resource, electrolysis and similar water-splitting methods have attracted the interest of the scientific community. With the objective of reducing the cost of hydrogen production, renewable sources of energy have been targeted to allow electrolysis.[13]...
Importantly, sustainable biomass is a limited resource and the value of using biomass for CDR via BECCS may exceed the value of using biomass for bio-energy production only [41,42]. For this analysis, we focus on European nations given their pledge to reach net-zero greenhouse gas emissions ...
As an artificial photosynthesis design, here we demonstrate the conversion of swimming green algae into photovoltaic power stations. The engineered algae exhibit bioelectrogenesis, en route to energy storage in hydrogen. Notably, fuel formation requires no additives or external bias other than CO2 and...
